I know lots about strain gauges, I have used them extensively in previous jobs. The fun thing here is that the probe head has only two contacts (a screw with a gold-plated cone in the middle). I am starting to wonder if it is working on a protocol like one-wire. The head contains LEDs, and I don't know what else. There is automatic nulling but that might be in the interface unit. > What is really needed to fix that is gold-plated > (maybe gold over nickel over copper?) balls and > bars, but it's hard for DIYers to do that, Have you considered tungsten carbide?

Well, so far I have concluded that it is the thing least likely to come apart easily that I have considered taking apart.... -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1916 ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
